hi – new to this forum, so i’m sorry if this is as dumb as it might be…

I design publicity as a volunteer for a non-profit & i’m trying to save out a tiff (& a jpeg, to email as a rough proof) of an image i’ve converted to tritone in PSCS (to create a sepia effect from a grayscale original). i haven’t used tritones before now…

only being offered a few file formats in the save as dialog (psd, pdd, eps, pdf, pdp, & raw). is this because only these formats support tritone, and if not, is there any reason why only these formats are being offered?

I reset my preferences but no change. the grayscale original comes up with all the usual options to save as (psd, tif, jpeg, etc.).

converting to rgb messes up the colors, which is no good. if i have to convert the color mode, any suggestions how i can get a tiff with the colors unchanged? (color management is not my strong point…)

once again, sorry if this is dumb, but i did try to find answers in PSCS Help and elsewhere before bothering you guys with this, but came up a blank.

yes

I would recommend saving as a PDF, most people shoould be able to read them without problems.

ok, rene – many thanks. not sure the recipient does have anything to read pdfs, as it goes, but he can download a Reader, i guess!

Kelsang,

PDFs are very common on the Web now, so that anyone who does much surfing on the Internet gets reminded frequently to download the Adobe Reader for PDFs.

burton,

you’re right, but i’m dealing with my teacher – a buddhist monk who’s not at all what you’d call tech-savvy… (not that i am, really, but compared with him i’m a hacker!)

also, i realised i can save to pdf in PS, then to jpeg in Acrobat, so the proof’s in the can.

still struggling with color conversion though, tritone to cmyk for offset… my screen’s calibrated well enough for me by eye using the print bureau’s charts etc, but i don’t understand enough about color to know what to do about the perceived color shift when the tritone image is imported into the InDesign document it’s a part of & converted to cmyk… i want my print to be as close to the colors in the original tritone image (on my screen) as possible. where can i find out more about this (in idiot proof terms…), or can anyone offer advice?

many thanks again,
jigme

And…I think…(someone chime in if this is inaccurate), but tritones (as well as duotones) need to be saved as an eps file – not a tiff. As the others said, maybe pdf is the best bet but you might also try saving as an eps.

Jigme,

still struggling with color conversion though, tritone to cmyk for
offset<<

Duotones are normally printed with spot inks, not process, and you need to save as EPS to retain the spot colour data.

If you wish to print using Process inks, then it would normally be easier to work in CMYK and then colourize through Hue & Saturation (although the effect may be slightly different)

ok, thanks guys –

I guess i’ll get a quote for the job in spot inks & save the image as an eps file, and a quote for another version in cmyk using a hue/saturation adjustment as close as i can get it – then it’s up to them which to go for!

many thanks for all your help. i’m going to go learn about color… 🙂
